Walmart offers the Lasko 16" Oscillating Floor Fan in White for $12.88. Opt for in-store pickup to avoid the $5.99 shipping charge. That's $3 below our July mention and the lowest price we've seen. (It's the best deal now by $10.) It features a 32" to 47" adjustable height, three speeds, and tilt-back head.

Update: The price has increased to $13.88.
